Tony Campana nearly joined the list last summer, but the Cubs declined a White Sox’s trade proposal for the scrappy speedster.

Ron Santo, however, wrapped up his 15-year career on the South Side in 1974. He spent the majority of the season as the DH hitting .221, 5 HR, 41 RBI–the lowest totals of his entire career.

Santo’s move south was actually part of a trade that brought Steve Stone to the Cubs in December of 1973. Stone spent three rather mediocre seasons on the North Side compiling a (23-20, 4.04) record before rejoining the White Sox for 1977-78, where he won 27-games total during the following two seasons.

Ten years later the Rangers traded Sammy Sosa to the White Sox in July of 1989. He played another two seasons for the White Sox hitting .227, 28 HR, 113 RBI all totaled before being shipped to the North Side for George Bell in March of 1992.

Sosa was 23 when he arrived with the Cubs and of course went on to hit 545 home runs with the club to become the franchise’s all-time homerun leader.
